Rt®-βDEXm:
- General-purpose chiral phase with many published applications
Rt®-βDEXsm:
- Excellent column for most chiral compounds in essential oils
Rt®-βDEXse:
- Similar in performance to Rt®-βDEXsm but provides better resolution for limonene, linalool, linalyl acetate, ethyl-2-methylbutyrate, 2,3-butane diol, and styrene oxides
Rt®-βDEXsp:
- Often useful in dual-column configurations, with the Rt®-βDEXsm column, for complex enantiomeric separations
Rt®-βDEXsa:
- Unique selectivity for esters, lactones, and other fruit flavor components
Rt®-βDEXcst:
- Proprietary stationary phase, developed specifically for the fragrance industry
- Also used for pharmaceutical applications
Rt®-γDEXsa:
- Suitable for larger organic molecules
- Also useful for flavor compounds in fruit juices
Rt®-2560:
- Stationary phase selectivity optimized for isomer separation to ensure accurate quantification of critical cis/trans FAMEs (Fatty Acid Methyl Esters)
- Application-specific QC test guarantees consistent, reliable performance for AOAC 996.06 and AOCS Ce 1j-07 methods
- Excellent sample capacity; no peak distortion means easy, accurate peak integration
Rt®-TCEP:
- General-purpose columns, ideal for aromatics and oxygenates in gasoline
- High polarity provides a retention index for benzene over 1000
- Separates alcohols & aromatic compounds from aliphatic components in gasoline
